Viktor Barzin 2be858f616 fix: eliminate memory overcommit to prevent node OOM crashes 
Set requests = limits (Guaranteed QoS) across LimitRange defaults and
explicit pod resources. Node2 crashed 2026-03-14 from 250% memory
overcommit (61GB limits on 24GB node).

Changes:
- LimitRange: default = defaultRequest for all 6 tiers
- Grafana: 3 → 2 replicas
- Grampsweb: document why replicas=0
- Prometheus: 1Gi/4Gi → 3Gi/3Gi
- OpenClaw: 512Mi/2Gi → 768Mi/768Mi
- Immich server: 256Mi/2Gi → 512Mi/512Mi
- Immich postgresql: 256Mi/1Gi → 512Mi/512Mi
- Calibre: 256Mi/1536Mi → 256Mi/256Mi
- Linkwarden: 256Mi/1536Mi → 768Mi/768Mi
- N8N: 256Mi/1Gi → 512Mi/512Mi
- MySQL cluster: 1Gi/3-4Gi → 2Gi/2Gi
- pg-cluster (CNPG): 512Mi/4Gi → 512Mi/512Mi
- DBaaS ResourceQuota limits.memory: 64Gi → 12Gi

git-crypt setup

To decrypt the secrets, you need to setup git-crypt.

  1. Install git-crypt.
  2. Setup gpg keys on the machine
  3. git-crypt unlock

This will unlock the secrets and will lock them on commit
